QUESTIONS
◉ Which of the following is not a proper technique of custom
shaping of a catheter?
A. the cut tip should be smooth
B. shape the tip in hot water
C. fix the tip in cold water
D. punch side hole opposite one another. Answer: Answer: D
◉ Which of the following are inversely proportional to contrast
delivery rate?
1. catheter length
2. catheter diameter
3. more side holes
A. 1 only
B. 2 only
C. 3 only
D. 1, 2, and 3. Answer: Answer: A
,◉ How long is the injection time for 30ml of contrast media
delivered at 3.7ml/sec?
A. 0.1sec
B. 4.5sec
C. 8.1sec
D. 111sec. Answer: Answer: C
Injection time is calculated as volume/time, so 30/3.7=8.1 seconds.
◉ What is the primary reason that guide wires must have a flexible
tip?
A. to permit bending and avoid damage to vascular walls
B. to permit whip lash to occur
C. to avoid unraveling
D. to avoid clotting. Answer: Answer: A
The primary reason guide wires must have a flexible tip is to permit
bending and avoid vascular wall damage.
◉ What term describes the thin wire along which a catheter will be
threaded when it is inserted into a vessel?
A. French catheter
B. Seldinger needle
C. guide wire
,D. J wire. Answer: Answer C
◉ Which of the following increases the flow rate of contrast media?
A. decreased pressure
B. decreased viscosity
C. increased catheter length
D. decreased catheter diameter. Answer: Answer: B
Decreased viscosity of contrast material will increase the flow rate.
Decreased pressure, increased catheter length, and decreased
catheter diameter will all decrease the flow rate.
◉ Which of the following is not part of the Seldinger technique?
A. a compound needle pierces the artery completely
B. the artery is opened surgically
C. a guide wire is introduced through a compound needle
D. the guide wire is removed. Answer:
◉ Which of the following basic components are part of an automatic
injector?
1. high pressure mechanism
2. contrast material
3. heating device
, A. 1 and 2 only
B. 1 and 3 only
C. 2 and 3 only
D. 1,2, and 3. Answer:
◉ Which of the following film sizes are used for cinefluorography?
1. 8mm
2. 16mm
3. 35mm
A. 1 and 2 only
B. 1 and 3 only
C. 2 and 3 only
D. 1,2, and 3. Answer:
◉ What term describes the size of a needle lumen?
A. cannula thickness
B. coil size
C. core size
D. gauge. Answer: Answer D
The needle lumen is identified by a gauge number. The higher the
gauge number, the smaller the inner diameter of the lumen and vice
versa.
